A series of eruptions occurred from the volcano over the past few days.
During 3-5 January the explosions generated an ash plumes that rose to estimated 10,000 ft-12,000 ft (3,000 m-3,600 m) altitude and drifted W-SW direction. Visibility of the explosions are limited due to dense clouds.
Incandescent blocks from the actively growing lava dome slid down over the slopes and caused avalanches of material.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 3 km distance from the main crater and 5 km on the SE flank and 4 km on the NE flank.
The Volcanic Alert Level remains at Orange.
